SHOEMAKERS MACHINE.

Application 'fiIed'May 13, 1919. Serial No. 2%,901.

To all whom it may concern:

Be it known that I, HIsKIAs MUINONEN, I

be used for sewing either leather soles or rubber soles.

Another object of the invention is to provide means whereby the change may be .made quickly and easily and without the use of any special tools. I

' The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, in wh1ch:

Figure 1 is a front view of a cap provided with my improvement;

Fig. 2 is a like view with the parts in a different position; I

Fig. 3 is a perspective view of the cover plate which is used when rubber soles are to be sewed.

In these views 1 indicates the needle plate cap and 2 indicates the needle plate which is carried by said cap. This plate is 'provided with the needle hole 3 which is of substantially keyhole shape. This plate also carries a cutter 4 for cutting the grooves in the leather soles.

By making the opening as shown, there is Qno danger of the sides of said opening scraping-the wax off the thread as with the openingsas now made. This style of opening also prevents the loop opener from breaking the thread or needle.

When the machine'isused for sewing rubber soles it is not desirable-to use the knife or cutter as this would cut a slit in the rubber causing it to break. In order to prevent this cutting of the rubber soles, I provide a second needle plate 5 which is secured to the inner end of the first plate and to the cap by the screw 6. This screw permits the second plate to be swung away from the first plate or to be moved into a position over said plate when rubber soles are to be sewed. This second plate is provided with an opening 7 which is of the same shape as the opening in the first plate but this opening is provided with an extension 8 at its inner end for receiving the cutter when the second plate is swung over the first plate. This second plate is of suflicient thickness to entirely inclose the cutter to prevent it from coming in contact with the rubber sole. The rear edge of said second plate is provided with a flange 9 which extends at right angles to the plate and forms a stop to hold the second plate in correct position over the first plate, said flange engaging the edge of the first plate.

It will thus be seen that the machine can be used for sewing either leather or rubber soles and that the change from one to the other can be quickly and easily made by simply swinging the upper plate into and out of operative position.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that. I may Patented Mar. 9, 1920.

make changes in the construction and in the 1 combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim 1s: A shoe sewing machine comprising a needle plate cap, a needle plate carried thereby and having a keyhole shaped open-' 'ing therein, a cutter on said plate, a sec ond plate pivoted to the first plate and-
